我无法使用 spring 启动连接到 mongo db atlas

Question

我有一个 spring 微服务应用程序链接到 mongodb atlas 数据库，昨天我的项目工作正常但今天我收到这个错误

这是我的 application.properties 文件

spring.data.mongodb.uri=mongodb+srv://denver:*****@product-service.wt2swod.mongodb.net/?retryWrites=true&w=majority
spring.data.mongodb.database=product-service

eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

spring.application.name=product-service
server.port=0

我试图添加这些属性但从未奏效

@SpringBootApplication(exclude = {
  MongoAutoConfiguration.class, 
  MongoDataAutoConfiguration.class
})

Answer 1

我建议您 -> 将 socketKeepAlive 设置为 true（在最新版本的本机驱动程序中默认为 true）-> 设置 maxConnectionIdleTime <.net.ipv4.tcp_keepalive_time 这样您的 JVM 将获得连接而不是反过来。

Answer 2

当我通过本地机器连接到 Atlas 集群时，我遇到了同样的问题。 我不得不再次通过 Atlas 仪表板将我的 IP 地址列入白名单。

将您当前的 IP 地址列入您的 mongo 数据库集群中的白名单
